Abstract

To aim at the reduction of the capacity in external DC power source for the supply of power for snow-melting and to prevent the problems from occurring in presence of defective strings, the present invention comprises individually switchable current ON/OFF apparatus provided for each string and control apparatus for individually controlling the ON/OFF of said current ON/OFF apparatus, thus enabling current is applied to each single string in sequence.
